The choroid is the layer of blood vessels and connective tissue between the sclera(white of the eye) and retina. It is part of the uvea and supplies nutrients to the inner parts of the eye. Inflammation of the choroid is called choroiditis.

What are choroid bodies?
what are choroid bodies?
Cerebrospinal fluid is formed by capillary knots?
Choroid Plexuses
What color is the choroid?
choroid is black in colour with a lot many nerve fibres to nourish the organ that is eye.
What is the color of choroid?
The choroid is typically dark brown due to the high concentration of blood vessels in this layer of the eye. This pigmentation helps absorb excess light and prevent glare within the eye.
Which two involuntary muscles are located in the front part of the choroid?
One of the two muscles that make up the front part of the choroid is the ciliary muscles. Another one that makes up the choroid is the iris.
What is the damage to the choroid plexus would interfere with?
Damage to choroid plexus would interfere with the production of CSF (cerebrospinal fluid).
Where is cerebrospinal fluid made?
Well, the theory right now is the majority of CFS is produced within the ventricles the choroid plexus produces by a combined process of diffusion, pinocytosis and active transfer of arterial blood and the rest is produced by modified ependymal cells of the choroid plexus.
What is the vascular middle layer of the eye that provides the eye with blood called?
This is the middle layer of the eyeball and it is composed of the choroid, ciliary body and iris.
Where is CSF made?
choroid plexuses
What forms the bulk of the heavily pigmented vascular layer?
The choroid forms the bulk of the heavily pigmented vascular layer.
The choroid and the auricle are similar because?
they both serve as structures that support the functioning of other organs. The choroid is a layer in the eye that provides blood supply and nourishment to the retina, while the auricle (external ear) helps collect sound waves and directs them into the ear canal for processing by the inner ear structures.
What is the function of choroidea?
The choroid, also known as the choroidea or choroid coat, is the vascular layer of the eye, containing connective tissue, and lying between the retina and the sclera. The human choroid is thickest at the far extreme rear of the eye (at 0.2 mm), while in the outlying areas it narrows to 0.1 mm.[1] The choroid provides oxygen and nourishment to the outer layers of the retina. Along with the ciliary body and iris, the choroid forms theuveal tract.
